PATIENTOFFICE-* TIDE Moroni' To all whom, t may concern.'

Be it known that we, HERMAN SAUER, a citizen of Germany, and HENRY SAUER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and usefulImprovements in Tide Motors, of which the following is a specification.

The present invention relates to improve# ments in tide motors, and it is the principal object of the invention to provide a iloat operated motor including means to store a supply of water for operating the motor during the intermission of the tide movements.

Another object of the invention is the provision of a motor of this character which is simple and inexpensive and which allows a continuous operation during the intermission in the tide movements avoiding all interruptions in the operation of the motor.

A still further object of the invention is the provision of a motor comprising a frame and a tank carried by said frame at an elevation adapted to be filled by a pump operated by the motor, and allowing a distribution of the water pumped into said tank during the intermission in the tide motion to drive a rotor shaft from which the power developed is taken to drive a driven part of machinery.

These and other objects and advantages of our invention will become more fully known as the description thereof proceeds, and will then be specifically pointed out in the appended claim.

In the accompanying drawing, forming a material part of this disclosure The figure is a front elevation of a form of our device, partly in section.

In the device, the floating body 52 carries a boss 53 to which the lower end of an arm 54 is attached, the upper end of which is pivotally secured to one end of an arm 55 of a bell crank-lever having its pivot point at 56 on a bracket 57 secured to the floor 58 of the frame for the device, including posts 59 connected by beams 60 and cross-beams 61. The other arm 62 of the bell-crank lever has attached to its upper ends a link 63, the opposite end of which is attached to a sleeve 64 fixed on the piston rod 65 which carries pistons 66 and 67 on its ends working in cylinders 68 and 69 respectively, resting on parts of cross-beams 70 and 71.

Posts 72 and 73 are connected by crossn beams 74 and 75 on which rests the bottom of a tank 76. Near its upper end, the tank 76 is connected by a pipe 77 with a small pump within a casing 78, which is also connected by means of a suction pipe 79 with the water. On cross-beams 80 of the machine frame rests a platform 81.

A pipe 82 is connected to cylinder 69 while a similar pipe 83 is connected to cylinder 68. Both pipes 82 and 83 are connected by a cross 84 and are controlled by valves 85 and 86. The cross 84 is connected by a pipe 87 controlled by a valve 88 with the tank 76.

The cylinders 68l and 69 are rovided at vtheir outer ends with nipples 8 and 88 in which are connected pipes 89, controlled by valves 91 and 92 on opposite sides of a cross pipe tting 90 into which the pipes 89 lead.

A turbine is arranged within a casing 93 which is connected with the crosses 84 and 90 by suitable pipes, and a pipe 94 controlled by a valve 95 leads from the cross 9() into the water. The shaft 96 of the turbine carries a small pulley 97 to which a belt 98 is guided over a pulley 99 on the shaft of the pump within the casing 78. The shaft 96 carriesalso a large pulley 100 from which the power is taken to drive machinery.

The device operates as follows During the movements of the Hoating body caused by the rising or receding tide, the pumping system 68, 69, 66, 67 will operate to drive the turbine by the proper regulation of the valves, and to operate l pump 78 to fill the tank which will allow the water therein by the proper regulation of the valves to drive the turbines during the interval between the rising and receding tides which is about one hour.

Changes may be made in the general arrangement and in the construction of the minor details of my invention without departing from the spirit and scope of the same as specified in the claims hereto appended.

Having thus described our invention, what we claim asnew and desire to secure by Letters Patent, is

In a tide actuated pump, the combination with a frame including a platform fixed over a body of water subject to tide uctuations,

relation on said frame, pistons operable in said Cylinders, a piston rod connecting therebetween, a float movable on the Water below said frame, a bracket rigid on the platform of said frame, a bell-cranklever 5 pvoted on said platform, link" connections between the arms of said bell-crank lever` and said float and piston rod, valved con neotions between the outer ends of said cylinders, and a tank to which both cylinders are connected. 10

In Witness whereof we have axed our signatures.

HENRY SAUER.
